A simple feature that is missing in this game when it comes to descriptions and clarity.
For starters, there are terms that are never mentioned anywhere and never explained, yet behave in a completely unnatural or non-instinctive way.
“When the troop is damaged.”
“Heal the troop.”
“Give life to a troop.”
“Create 15 X and Y gems.”
“Create 15 gems, a mixture of X and Y.”
“Gain X gold.”
“Steal X gold.”
“Another random ally.”
“Random status effect.”
“When dealing skull damage”
“Damage from skulls.”
And last but not least.
“First 2 enemies.” / “Last 2 enemies.”
“First and last enemies.”
Some of these effects are already figured out by veteran players, but frankly, I have been playing this game for almost a year, and some people who play this game much longer had no idea how these mechanics really work, though playing for almost 2 years. Especially the wounded and health referring mechanics.
Clarification is required (As mentioned by @Lyya , one such example is “extra turn” upon matching 4/5 gems or triggered by spells, which would indicate triggering traits that take effect each turn) and mechanics’ descriptions should be uniformed in case they do the same thing (15 gems of X,Y reference).
